Agree.  Another issue is enum, for example,

public enum SomeEnum{
    enum1, enum2, enum3

I think the mimic will look like:

public final class SomeEnum extends Enum{
    public static final SomeEnum enum1 =  new SomeEnum("enum1", 0);
    public static final SomeEnum enum2 = new SomeEnum("enum2", 1);
    public static final SomeEnum enum3 = new SomeEnum("enum3", 2);

    protected SomeEnum(String name, int |ordinal|){
       super(name, ordinal).

and of course, the abstract class Enum(declaration without generics of 
course) must exist at first. 

Thoughts?  I will raise a jira about Enum abstract class and create a 
patch later to support this mimic if this approach is fine.
